But Palin’s camp denied the report to POLITICO, and the Des Moines Register writes Monday that the "aide" cited by the British account is an out-of-town doctor affiliated with "Physicians for Palin" planning to come to Iowa for the former Alaska governor's book signing.

Palin, just days away from a weekend swing through Iowa, is doing what she does best: generating buzz about her political brand and drawing speculation about her plans for 2012. (See: Palin says she can defeat Obama)

Recent comments from two prominent Republican figures reveal the division in the party when it comes to Palin's political future and a possible presidential bid. (See: Sarah Palin says she's pondering 2012 run.)

Former Arkansas Gov. Mike Huckabee, a potential GOP presidential candidate himself, told reporters in Des Moines on Sunday he believed Palin would be a "force" to be reckoned with were she to throw her hat in the ring and that Republicans should be "prepared" for the 2008 vice presidential nominee to "run away" with the primary election.

Palin's visit to Iowa on Saturday will make her one of three Republican presidential hopefuls to travel to the key primary state this month, with Huckabee and former House Speaker Newt Gingrich having also taken tours of the heartland state. (See: Huckabee to push social issues in Iowa)

Huckabee, who like Palin, has a regular gig on Fox News, joked at his availability. “If I get in, I prefer she not and that she endorse me.” Huckabee has said he will enter the race if he feels he has a clear pathway to victory. (See: Sarah Palin, Mike Huckabee blast NPR)

Meanwhile, former first lady Barbara Bush taped a segment with Larry King slated to air Monday night in which she indicated she was not keen on Palin campaign, suggesting that the former Alaska governor should stay in her home state where she is happy.

"I sat next to her once, thought she was beautiful," Bush said. "And I think she's very happy in Alaska, and I hope she'll stay there."
